A steel ball with a volume of 100 cm3 moves at a constant speed of 36 km / h. What is its momentum?

To find the momentum on we need mass and speed, and to find the mass we will use the formula
m = ρ (steel) V
And with a single formula it is written like this
p = ρ (steel) V * V
But before substituting the values, we convert 36 km / h into m / s, this is 10 m / s, and it turns out
p = 7.8 * 0.1 * 10 = 7.8 (kg * m / s)
Answer: p = 7.8 (kg * m / s)
